OneCircle Launches KeyKeg Type-A Valve for Universally Compatible Filling and Dispensing

OneCircle (commonly known as KeyKeg), the inventor and global leader in sustainable kegs for the beverage industry, proudly introduces  the KeyKeg A valve, the latest addition designed to make filling and dispensing easier and more efficient. KeyKeg A seamlessly integrates into existing A-fitting dispensing systems, offering a hassle-free integration for beverage professionals worldwide.

Designed for Simplicity and Efficiency

KeyKeg A is built with brewers, wine producers, and hospitality professionals in mind. Featuring a universal A-fitting, it ensures effortless compatibility with widely used dispensing systems in Europe—eliminating the need for additional equipment. This means easier handling, smoother operations, and consistently great pours.
Onno van Steijn, CEO of OneCircle, shared:
“Listening to our customers has always been at the core of our business, and KeyKeg A is a testament to that approach. By working closely with brewers and wineries around the world, we are now launching the A fitting, which will simplify their day-to-day operations and will improve the high-quality beverage beyond their expectations. We are excited to be opening the door to new opportunities in the KeyKeg world, paving the way for both existing and new customers to jointly strengthen successful, sustainable businesses worldwide.”

Key Advantages of KeyKeg A: 

•    Universally Compatible – Designed for A-coupler systems, making it a perfect fit for many European and global markets.
•    No Extra Investment Needed – Integrates seamlessly into existing A-fitting systems without additional equipment.
•    Maximised Shelf Life – Bag-in-Keg™ technology ensures beverages stay fresh longer, without oxidation or contamination. This multi-layered protection preserves high-quality flavours and maximises shelf life. It keeps beverages separate from the propellant gases used to dispense.
•    Damage-resistant –Double Wall™ Technology makes the kegs strong, durable, and resistant to damage, keeping your beverages safe during transport and handling.  
•    Perfect for Wine & Beer – Unlike steel kegs requiring CO2 or nitrogen, KeyKeg A allows your drinks to be tapped using compressed air.
•    Lightweight design –  The ergonomic grip ring and basecup make lightweight kegs both stable and easy to handle. You can move, stack and load empty or filled KeyKegs by hand. •    One-way export solution – Unlike steel kegs, KeyKegs require no deposit, return logistics, costly cleaning or financial risk from damage or theft. 

Testing KeyKeg A with customers

Mark Bakker, Chief Technology Officer at OneCircle, recently conducted filling tests using the new KeyKeg A valve in collaboration with our customers, Naparbier and Brouwerij De Meester. The results were remarkably positive. 
“We were thrilled to test KeyKeg A in our brewery, and the results exceeded our expectations. The new A-valve made filling incredibly efficient. We love collaborating with people who are passionate about beer and innovation. We’re excited to start using KeyKeg A on a larger scale.” shared Juan Rodríguez, Co-Founder and Brewmaster at Naparbier.

Dirk de Meester, Owner and Master Brewer at Brouwerij De Meester said:
“Integrating KeyKeg A into our filling process was pretty simple. Its compatibility with A-fittings meant we could continue using our existing setup without any modifications. KeyKeg A has proven to be reliable, and our team appreciates its lightweight design and the ease of filling.”
